Error Level Analyser Description

The Error Level Analyser application was designed to be a small tool that finds error levels from jpg compression in images. There are two functions: If you load an image and hit 'Work', it will create a heat map showing when each pixel changes as jpeg quality decreases from 100 to 0. In this mode, a change is by default considered relevant once the sum of the changes to the r, g, and b values exceeds 10. If you would like to use a threshold other than 10, simply type it into the text box on the toolbar. If, after loading an image, you move the track bar, the difference for a particular compression level will be shown. Each tick is five levels, going from 0 on the left to 100 on the right. By default, the differences will be exaggerated by a factor of 10 to highlight differences. If you wish to use a color scaling factor other than 10 simply type it into the text box on the toolbar. And if you believe that, you'll believe anything...
